I think if you want the public to accept that the government will be a better shepherd of this money than a decentralized smattering of individuals then the government should provide evidence for this, once it actually opens up from a dysfunctional shutdown.
At least in the American context everything from California High Speed rail to bloated defense spending has shown that VC’s are much better shepherds of their own money.
Completely agree, the American government has become incompetent in delivering any real big project to its citizenry, it went through a whole ideological process of gutting its abilities to do so.
It was designed to lose this ability, and to lean onto private enterprises to do anything but in the past the government was able to rollout highways, go to the moon, build dams, bridges, power plants.
If both the government and VCs are now unreliable to shepherd capital to direct it to the improvement of society at large you might need to rethink the whole system, and work to nudge it into a better path.
